China’s Electric RX4E Becomes First to Obtain Type Certification

In a significant milestone for China’s aviation industry, the RX4E, a domestically developed four-seat electric aircraft, has become the first of its kind to receive type certification from the Civil Aviation Administration of China (CAAC). This achievement marks a breakthrough in new energy aviation technology and paves the way for the aircraft’s mass production.

The RX4E stands out as the first fully electric aircraft designed under China’s civil aviation regulations for airworthiness in the normal category (CCAR-23), which covers small aircraft. Receiving a type certificate is a crucial step for any aviation product before it can enter mass production.

Developed independently by the Liaoning General Aviation Academy of Shenyang Aerospace University, the RX4E boasts impressive specifications. With a wingspan of 13.5 meters and a length of 8.4 meters, it has a maximum takeoff weight of 1,260 kg. The aircraft is powered by a lithium battery pack with a total capacity of 70 kWh, and its electric propulsion system delivers a maximum output of 140 kW.

One of the RX4E’s notable features is its maximum flight time of 1.5 hours. It offers several advantages, including zero emissions, low noise levels, reduced operational costs, and high safety and reliability. These benefits make it an attractive option for various applications such as pilot training, sightseeing flights, experiential flying, aerial photography, and aviation surveying.

Looking ahead, plans are underway to develop variants of the RX4E for water and snow operations, as well as models powered by hydrogen propulsion. These developments aim to expand the aircraft’s usability and enhance its competitiveness in the market.

Under Chinese aviation regulations, small aircraft are classified as normal-category if they have 19 or fewer passenger seats and a maximum certificated takeoff weight of 8,618 kg or less. The RX4E fits within this category, aligning with the standards set for small aircraft in the country.

The journey to obtain the type certification began on November 11, 2019, when the CAAC accepted the RX4E’s design application. Over the past five years, the development team has completed all necessary airworthiness verification work, culminating in the successful certification of the aircraft.

The certification of the RX4E not only represents a significant technological advancement but also signals China’s commitment to innovation in sustainable aviation. As the aviation industry globally seeks eco-friendly alternatives, the RX4E positions China as a key player in the development of electric aircraft technology.
